Experimental study of dehydrating properties of pumpkin chips in vacuum drying;

The test study the dehydrating properties of straw mushroom,which show how the moisture content and dehy-drating rates of the straw mushroom vary with the infrared-drying time respectively,have been acquired for the purpose of describing quantitatively dehydrating properties of straw mushroom.

In order to investigate the impact of the rotor-to-stator axial spacing on the compressor stalling characteristics, experimental studies for characteristics of the low speed research compressor with different rotor/stator gaps had been carried out.
